Control method of fire alarm device

Abstract

The invention provides a control method of a fire alarm device. According to the control method of the fire alarm device provided by the scheme, an information processing module firstly judges whether received smoke concentration data and combustible gas concentration data exceed corresponding threshold values or not and whether received environment temperature data and infrared temperature data exceed corresponding threshold values or not; and if any data exceeds the corresponding threshold value, a CCD camera is started to carry out image acquisition, and detection data is converted into an electric signal to be transmitted to an information processing module. According to the method, a multi-situation working mode and a segmented judgment method are adopted for multiple sensors, a temperature sensor, a smoke sensor and an infrared temperature sensor are firstly used for rapid rough inspection, and if problems exist, the CCD camera is used for fine image detection, so that the detection comprehensiveness is improved, the detection efficiency and quality are ensured, processing and operation time of the information processing module is shortened, real-time performance is improved, and system life is prolonged. Under the normal condition, low-power-consumption operation is achieved, and short-time overclocking operation can be achieved under the condition that complex programs or multiple tasks are processed.

Description

technical field [0001] The invention relates to the technical field of fire smoke detection and alarm equipment, in particular to a control method of a fire alarm device. Background technique [0002] With the continuous improvement of the economic level and industrial level, the number of various household appliances and industrial equipment has increased rapidly, and the electrical equipment has also continued to expand. The hidden dangers of fire safety in various production workshops have also increased, and fire accidents have occurred frequently. Among the many fire accidents, the probability of fires in various chemical plants, fuel plants, natural gas plants, and kitchen natural gas stoves will be higher. Most chemical plant fires are prone to produce acidic gases, which are highly toxic and corrosive. Natural gas cooktops in kitchens are prone to dry burning or fires caused by gas leakage. Gas plants are prone to gas leakage, especially in areas prone to natural ...

Problems solved by technology

If a misjudgment is made, it means that there is no danger and emergency measures are taken, causing unnecessary trouble

And the sensor does not work in time-sharing, which increases the processing and running time of the CPU and reduces the real-time performance and system life

[0005] Therefore, in view of this current situation, it is urgent to design and produce a control method for fire alarm devices to solve the problem that there is no effective control method for fire alarm devices in the prior art, the comprehensiveness of detection is low, and misjudgment or misjudgment is prone to occur. In the case of missed judgment, the sensor does not work in time-sharing to collect information, the CPU processing and running time are long, the real-time performance and the system life are low.
